EMBRQIDERI SPECIFICATION forming part of Letters NG-MACHINE Patent No. 281,231, dated July 17, 1883.

Application filed November 13, 18%9. (No model.)

To all whom it may concern:

Be it known that 1, JOHN BEcKER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Embroidering or Sewing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invent-ion has for its object the produc tion of an organized mechanism or apparatus for attachment or addition to an embroidering or, sewing machine of any usual construe t-ion havingauniversal feeding device to move the fabric or material in any desired direction, whereby the said feeding device may be automatically moved to feed the material in a circle of greater or less radius, or to so inovethe said material asto enable the needle to produce on the fabric, with itsthread, lines of stitches varying more or less from a true circle or from a straight line. A

In this my invention I employ an actuatinggear which acts directly or indirectly to rotate the universal feeding device, and I have provided a pattern-plate to move this gear so that it imparts a more or less irregular motion to y the said actuating-gear, and to the universal feeding device moved by it, whereby the fabric or material is moved in a more or less irregular line for the automatic production upon it by the needlethread of a figure such as is demanded by the shape of the pattern-plate 'employed, thus relieving the operator of the machinefrom all care in feeding or directing the material, yet enabling the exact reproduction continuously of any desired figure.

My invention also has for its object a novel manner of producing patterns for the reproduction of any desired figure, as will be hereinafter described.

My invention consists in certain features and organizations of mechanism, as will be hereinafter described in the specification and I Figure 1 represents in side elevation a sufficient portion of an embroidcring-machine of usual construction with my apparatus added to illustrate my invention; Fig. 2, a top or plan view of Fig. 1; Fig. 8, a top view of a part of my apparatus, sufiieient in connection with the parts shown in Fig. 2 to enable one to understand the method of producing a pattern-plate to be applied to the apparatus to effect the movement of the universal feeding device in definite directions, according to the figure desired to be produced upon the material by the thread being employed; Fig. 4, a detail of part of Fig. 3. Fig. 5 represents the figure which will be produccdwhen a pattern disk such as shown in Fig. 2 is employed.

Fig. 8 represents the figure which will be produced upon the material when the pattern-disk shown in Fig. 6 is employed. Fig. 9 is a top view of my apparatus, showing yet another form of pattern-disk; Fig. 10, a top view of Fig. 9; and Fig. 11 represents the figure which will be produced when the pattern-disk shown in Fig. 9 is employed; Fig. 12, sections of Fig. 1 on the dotted lines a? x and x Fig. 13 is a detail showing the eccentric stud A and a section thereof on the dotted line it; Fig. 14, a detail of the eccentric stud a? and bearing B; Fig. 15, a detail showing the stud-gear and pinion at its ends.

Referring to the drawings, wherein I have shown my apparatus applied to a Bonnaz machine, substantially such as represented in United States Patent No. 83,910, to which reference may be had, I have employed the letters of reference A Z R D W' L G H d c a on to represent parts the same as in the said putout; and it will be understood in the Bonnaz machine herein represented, to which my apparatus to be described is attached, that the needle A and universal feeding device or foot 6 will be operated as in the said patent; and it will be also understood that the said machine will in practice have as part of it the hand-crank, (marked S in the said patent,) by

' which to turn the univeisal feeding device and needle-bar in either direction. So the stitching devices and universal feeding mechanism, be ing well known and common, need not be herein further described.

In this my invention I apply to the usual needle-bar, A, a long pinion, A. Upon the arm A of the said Bonnaz machine I place my attachment, the foot-plate A of which is heldon the said arm by a suitable dog, A having a clamping-screw, A Upon the foot-plate A I place the frame-work A of the attachment; and to connect the foot and frame-work together so that the frame may be adjusted longitudinally, the upper side of the foot is provided with a rib, as shown in the section, Fig. 12, which co-operates with the under side of the frame-work A of suitable shape to fit. The frame-work A is slotted at its front end to receive the guiding-stud A, and at its rear endthe frame-work is provided with an eccentric stud, A, (shown separately in Fig. 18,) and having ahandle, A, by which it may be turned. The lower or eccentric portion of the stud A enters and fits between the walls of a slot, a, in the foot A", (see detail Fig. 13,) and as the said stud, held in the framework A by the screw A entering an annular groove of the said stud, is turned by the handle A, the frame-work may be moved backward and forward upon the said foot-plate, so as to insure the engagement of the intermediate gear, B, with the long pinion A on the needle-bar.

The frame-work A has bearings B B for the shaft B having upon one end of it the set of cone-pulleys Bf, driven by a belt, B which will extend from a corresponding but reverselyplaced set of cone-pulleys, (not shown,) but placed on theshaft-of the usual flywheel of the driving or treadle stand, the latter set of cones being located just between the stand and the inner side of the said fly-wheel, the transfer of .the beltv B from one to the other of the grooves of the said cone-pulleys operating in well-known manner to vary the speed of the shaft B with relation to the speed of the driver shaft of the stand, the shaftv to whichthe lower set of cones referred to is secured The forward end of the shaft B is provided with a bevel gear, B, which is adapted to be engaged at will with either of the bevel-gears B or B fast on the main shaft B of my apparatus. To enable the gear B to be engaged with either of the said gears B or B at will, so as to rotate the'shaft B in eitherdirection, I have made the bearings B B of the shaft B so as to permit the said shaft to rise and fall somewhat at its front end.

movement by a screw, a", which enters an annular groove-in the said stud. Upon thetop of the frame-work A is attached a stationary circular toothed track, a Upon the shaft B,

just above this stationary track, is placed loosely the actuating-gear O, for turning the needle-bar, needle, and universal feed continuously'in one'di-rection, or backward and'forward,or, rather, for imparting to the said nee-' main pinion a, drives the stud-gear O so that Figs. 1 and 2, the intermediate gear, B, being dle-bar and feed a continuous rotary motion, or a rotary reciprocating motion.

Placed loosely upon shaft B, above the actu ating-gear O, is the pattern-carrying arm 0, and to the latter is attached, preferably in an adjustable manner, by a screw, a", a plate, 0. The upper end of shaft-B is made to extend above this plate 0 and has attached to it the main pinion a, the said pinion being herein shown as forming part of the said shaft. The plate 0 has an intermediate gear, 0 attached to it in an adjustable manner by the screw 0*, and the said intermediate gear drives the stud gear 0 (shown separately in Fig. 15,) said stud-gear having at its ends pinions b b. The stud-gear G has its bearing in an adjustable collar, 0, attached to the pattern carrying arm 0 by a screw, 6 extended through a slot, b in the said arm, (see Figs. 2 and6,) and screwed into abottom plate, 0. (Shown clearly in Fig. 1.) The adjustment of the collar O upon the arm 0 permits the pinion b of the stud-gear to engage the teeth of the stationary 0 track a", as in Figs. 1 and 2, or to be disengagedfrom the said track, as it will be when the pattern-plate represented in Figs. 9 and 10 is employed, -as will be hereinafter, described.

Thepattern-plate D, shaped as represented in Fig. 2, to produce the figure represented in Fig. 5, is attached to the pinion b of the studgear 0 byascrew, b. As shown in the drawings, Fig. 1, the pattern-plate D has a hub, D attached to its under side by the set-screws b, the said hub fitting over the end of the gear I).

The intermediate gear, 0, driven by the 10 5 its lower pinion, b, in'engagement with the stationary track a is caused to travel around the said track and move the stud-gear O and H the pattern-carrying arm 0, and during this movement of the armthe rotation of the stud- 1 r0 gear on its axis will, it is obvious, cause the pattern-plate D to be rotated in unisonwith the said stud-gear C The actuating-gear O referred to has a socket, D adjustably attached to it by a set-screw, b and the said socket, split at one side, as shown in Fig. 6, has a binding-screw, 72 by which to tighten the said socket to properly hold in adjusted position a tool-post, D, provided with afinger, D adjustably attached to the said post by a set-screw, D. The socket D and toolpost and finger are so adjusted that the end of the said finger bears against the periphery of the pattern-plate being used, and the said finger is maintained in contact with the said pattern-plate 'by a suitable spring, herein shown as a spiral spring, b connecting the arm 0 and the actuating-gear C.

With a pattern-plate such as represented in in engagement with the pinion A on the nee-' dle-bar A, the shaft Bmay be started, and the gears B B awill drive the intermediate gear,

0 and, as before described, will'turn the patseen that it, by acting on the finger D cartern-plate on its axis,while the said patternis I.

moved in a circular path about the stationary track; and the said pattern-plate D thus having a planetary motion, I shall hereinafter designate it asa planetarypattern-plate. The finger 1), being held against the planetary pattern-plate by the spring b will cause the actnating-gear O to follow the said pattern-plate as it moves in a circle about the axis of shaft 13*; but, owing to the cam-shaped or irregular periphery of the planetary pattern-plate, it is obvious that the actuatinggear C will have an interihitting or reciprocating movement during its rotation about the shaft B, the extent and =frequency of the said reciprocating movements depending, it will be understood, upon the shape of the pattern-plate; or, in other words, the shape of the cam and its speed of rotation is such. as compared with the speed of rotation of the planetary arm that one counteracts the other, and practically results in temporarily keeping the actuating-gear O at rest. \Vith a cam such as shown in Fig. 2, the straightest parts of the figure in Fig. 5 are pro-, duced when the gear 0 is substantially at rest, and the curved parts when the finger D is moving toward the center of the pattern'plate. When a patternplate such as shown in Fig. 2 is used to make a figuresuoh as represented in Fig. 5, the needle-bar or the universal feed is not actually turned except in one direction; but the speedat which it is turned in that one direction is made variable.

It will be understood that the gear 0, if left to follow the planetary arm, and the patternplate did not rotate, would travel forward at a speed depending upon the speed of shaft B but as the pattern-plate also rotates, it will be ried by the gear 0 and held pressed against the said plate by a spring, will movethe said gear G backward in opposition to the-forward movement just stated, which will act to retard or eompletelycheck the forward movement of the gear C; and with a pattern-plate of proper shape the forward movementof the gearOmay be overcome or reversed to the extent of the length of the space 20 cut out of the said gear; as in Figs. 2 and 6. When the backward movement of the gear G by the pattern-plate is equal to the forward movement of gear 0 by shaft B*, it will be seen that practically the gear 0 will stand still; but if the finger D rests on a portion of the pattern-plate which is the are of a true circle described from the spur-gear, then the forward movement of thegear 6 will be dependent entirely upon the speed of shaft B, and a figure represented by a tiii'e'eircle would he formed on the material;

by t he thread.

Toproduce irregular curves, it is necessary to make the movement of the gear 0 variable, or fast and slow at intervals, and this may be done just in the proportion that the speed of the gear 0 derived from shaft B is permitted to exceed the movement of the said gear in the. reverse direction derived from the particular shape of the pattern-plate. Thevariation in speed of the gear 0 and of the universal feed is in proportion to the deviation of the pattern-surface from a true circle. The actuatinggear 0, having imparted to it a progressive but reciprocating movement during its rotation, will, it is obvious, turn thcintcrmediate gear, B, needle-bar, and usual universal feed mechanism in like manner, enabling the said feed to move the material upon which it rests in the proper direction, so that the usual needle will loop the thread delivered to it always in the proper line to produce on the material a line of stitches in strict accordance with the requirements of thepattern-plate, thus entirely relieving the operator of the machine from any care as to the feeding of the material.

In order to produce a set figuresuch, for instance, as shown in Fig. 8the said figure always having a fixed number of loops or curves, and then being repeated, it is necessary that the teeth of the stud-gear C be always a multiple of the teeth of theintermediate, C, so that'the complete figure will be produced during each complete revolution of the pattern-plate about its own axis. 'Io illus trate, Fig. 8 contains nine loops in nine different positions, six in the main part of the figure and three in the stem, the central loop of the stem being a very small sharp loop. Therefore the pattern-plate D (see Fig. 6, it being of the proper shape to produce the figure shown in Fig. 8) must be so geared with and driven by the main pinion c as to rotate once while the said main pinion rotates nine times, thus enabling the pattern-plate to reciprocate the actuating-gear as it is being revolved, so that it-will turn the needle-bar and feed :to automatically move the material under the feeding device in the direction required by the pattern to produce the said figure. InFig. 8 I have marked the loops 1 to 9. In Fig. 6 the pattern-plate D is attached directly to the in termediate gear, C. It will be understood that the shape of the planetary pattern-plate may be varied at pleasure, according to the figure to be produced by the needle-thread on the fabric or material.

To increase or decrease the n umber of stitch es in each loop or repeat ofa figure to be produced, it is only necessary to alter the speed of the shaft B, as before statedas, for instance, the faster the speed of the shaft B with relation to the speed of the usual stitching parts the less the number of stitches in each loop or repeat of the figure, and vice versa. =-In Figs. 9 and 10, I have shown another modification of my apparatus or attachment adapted to produce the figure represented in Fig. 11, or a figure produced by giving to the cloth or material a movement sufficient to produce a certain number of. stitches in one and then in another direction. In this modifica IIO tion the actuating-gear C has only a movement of reciprocation, and never makes a complete rotation, as in the plan previously described,

tionary, it being secured to the stationary track by the screw 0, extended through the plate G, and a hub, c, placed between it and the stationary track, the said hub extending down through and opening in the actuating-gear O. In this modification the pattern-plate D is secured to the stud-gear O and the collar C is so adjusted on the arm 0 as to disengage the pinion b from the stationary track a so that the stud-gear may be rotated by the intermediate gear, 0, when the arm 0 is fastened, as stated. In this modification the pattern-plate has only a movement of rotation about its own axis. The'stud-gear and the actuating-gear O are reciprocated by the action of the said pattern-plate on the finger D Instead of securing the pattern-plate upon the stud-gear, as in Figs. 9 and 10, I may, if

desired, attach apattern-plate to the intermediate gear, 0 as in the modification represented in Fig. 6, such position of pattern-plate enabling the production of more complex and intricate figures.

I do not limit my invention to the employment of an intermediate gear, 0, of any particular size, as intermediate gears of different sizes may be employed, according to the pattern desired to be produced.

Assuming that the figure delineated in Fig. 8 was produced while the bevel-gear B was in engagement with the bevelgear B and I should desire to reverse the figure, it is only necessary to engage the bevel-gear B with the bevelgear B to reverse the direction of movement of the apparatus. v

To automatically effect the reversal of the parts of the apparatus'to reverse the figure being formed, I may attach a series of tappets, (1 in an adjustable manner upon the actuat ing-gear C, and provide the eccentricstud (t with one or more suitable fingers or arms, d",

to be struck by the said tappets, the turning of the eccentric stud moving the gear B into engagement with one and then with the other of the gears B B Referring to Fig. 10, let it be supposed that the pin (1 at the right is about to strike the arm (1 to throw B into engagement with B", such movement will result in changing the direction of rotation of all the parts and of the gear 0, so that as soon as the pin d at the left of Fig. 10 arrives at d it will turn it back in the opposite direction.

In the drawings I have shown a variety of pattern-plates for producing different figures. The method of producing these pattern-plates is an important feature of my invention. It being desired to produce a certain figure in thread 'or silk upon the material by the usual.

needle, the operator will turn the universal feed by means of the usual crank-handle, represented below the bed-plate in Figs. 1 and 2 of the said Bonnaz machine,) taking care that the figure is made as perfectly as possible. Before starting, however, to produce the figure desired, a plain metal or stiff plate,

and the pattern-carrying arm 0 is made sta- 6 will be attached to either the stud-gear or the intermediate, 0 and the tool-post will be provided with an arm, efl instead of the finger D The arm 6 at its front end, is provided with an adjustable marker or point, e, to work or trace a line upon the plate 6 as the latter is rotated under the said marker or tracer, as in Fig. 3. In Fig. 3 it will be assumed that the operator has turned the universal feed by the usual hand-crank, during which time the needle-bar is also turned, and the latter, by

the gear A thereon, turns the intermediate gear, B, and the latter drives the actuatingwheel 0 and its parts to rotate the plate 6 The plate 0 having been marked or traced, all that part of it outside thelinetraced or marked thereon will'be completely cut away or removed, thus forming a pattern-plate which, employed as herein described of the patternplates D, will enable the automatic production upon the material of a figure-like the one just produced by the manipulation of the machine by the operator, and any number of the said figures may be produced rapidly and correctly without further care by the operator. I have provided the head of the machine with a stationary guide or support, (1*, for the needle-bar A, as in Fig. 1, so as to insure the proper engagement of the pinion A and intermediate gear, B. The belt E on the wheel E is extended about the larger belt-wheel of the treadle mechanism.

' It is obvious that the apparatus herein de scribed as of my invention may be employed to rotate or impart a rotary reciprocating movement to any usual universal feed by properly connecting the gear 0 therewith. v

I desire it to be understood that the intermediate gear, B, is not essential, but may be omitted, and the gear 0 directly engage pinion A, without departing from my invention. By adjusting the tool-post and finger, and placing the end of the finger in contact with the periphery of the pattern-plate more or less out of a straight line drawn through the stud-gear and the center motion of the toolpost, the figure to be produced on the material by the needle and thread may be more or less contracted or expanded.

Having described my attachment as added to a Bonnaz machine, I desire it to be understood that it may be added to other wellknown sewing-machines having a universal feedas, for instance, I may cause the actuating-gear O to engage and move a gear attached to an arbor having upon it an oblique cam fitted to slide in a ring-plate, as shown in United States Patent'No. 134,463, wherein the said gear is marked t and the oblique cam is marked'r.
